IMPROVEMENT IN PRINTING-PRESSES.

Specification forming part of Letters Patent No.-17S,3?.8, dated June 6, 1676; application filed March 31, 1876.

To all whom it may concern:

Be it known that I, ALBERT E. REns'roNE, of Oakland, in thecounty of Alameda and State of California, have invented certain new and useful Improvements in the Construction and Arrangement of Printin g-lresses, of which the following is a specification V Figure l is a plan view. Fig. 2 is a side elevation. Fig. 3 is a longitudinal sectional elevation. Fig. 4 is a section of the press-bed, chase, and furniture. Fig. 5 is a cross-section of the press-bed, showing the card-taker. Fig. 6 is a side or edge elevation of the card-rest and card-taker and Fig. 7 is a plan view of the same, and. Fig. 8 is a side elevation of the roll used for inking the forms.

A represents the frame of the machine B,

Y the slotted card-rest; O, the card-taker; I),

the spring to operate the card-taker; E, the card-gages and side holders F; the set-screws to operate the card-gages and side holders; H, the screws to adjust the gate; G, the gate to gage the thickness of the card and hold the same in place; X, the impression-roll; I, the inking-rolls to ink the forms; J, the fountain to supply the ink to the rolls; K, the cards to be printed; L, the spider or armholder to hold the sliding arms; M, the sliding arms to connect with the press-bed; N, the press-beds to hold the forms; 0, projections on the cardtaker to take the card; 1?, the pins to be operated upon by the wheels on the end of the ink-rolls to force down the card-taker while passing under the ink-rolls and prevent inking the same. Y is .the plate for the shoulder to operate against and gage the height to which the card-taker should rise. Q represents the driving-pulleys. It is the curved groove in the sides of the frame A, in which the rolls T pass to carry the press-beds around to and from the way \V, where the card is taken and carried under the impression-roll X to receive the impression. V, the the projection to depress the card-taker and draw the projection 0 down out of the slots in the card-rest B. S are set-screws to adjust the impression-roll.

The following is the operation of the same: The cards being placed upon the card-rest B,

and the pulleys Q being revolved, the forms are carried around upon the press-beds N, under the impression-roll X, to receive the impression; the projection V depresses the cardtaker and forces the projections 0 down out of the slots in the card-rest B, the projections 0 extending through'the slots and taking one card from the bottom of the pile, carrying it under the gate G, (which holds all the rest back in place the card is carried under the same, and the impression is made in the usual manner; the card is dropped at the end of the machine. The projection V draws the projections down so as to free them from the slots in the card-rest B. gently turn into the horizontal ways W W, the two forming a continuous guiding-path for the traveling bed, and thus giving an easy motion to the bed, and a long straight track, W W, within a small circle.

It will be seen that the wheels on the sides of the press-beds are only to operate in the curves to guide the press, and that the weight of the impression is received upon the ways V by the press-bed itself bearing directly upon the same when it is passing under the card-holder B and the impression-roll.

What I claim, and desire to, secure by Letters Patent, is-

1. The revolving or traveling press-beds 'N, in combination with the sliding selfadjusting arms M, the spider or arm-ho1der L, and the curved grooved ways R W, substantially as set forth.

2. The slottled card-rest 13, having projections V on its under side, in combination with the card-taker 0, having projections O, and being supported on springs D, substantially as specified. i

3. The combination of the slotted card-rest B, having projections V on its underside, the card-taker O, supported on springs D, and having projections O, with the three adjustable plates G E E, substantially as described.
